Acute is < 90 degrees.
If it measures 90 degrees, then it is called a right angle.
An angle that measures more than 90 degrees is called an obtuse angle.
I assume you mean a triangle. 180 degrees - 45 degrees - 90 degrees = 45 degrees
90+90+90+90
a right angle measures 90 degrees
Acute is < 90 degrees.
An angle that measures less than 90 degrees is considered acute. If it measures more than 90 degrees, it is obtuse.
The corner of a square measures 90 degrees which is a right angle.
If it measures 90 degrees, then it is called a right angle.
An angle that measures more than 90 degrees is called an obtuse angle.
Any triangle that has an angle measuring 90 degrees is a right triangle.
I assume you mean a triangle. 180 degrees - 45 degrees - 90 degrees = 45 degrees
the answer is 90 degreesA right angle measures 90 degrees. More than 90 degrees is an obtuse angle and less than 90 degrees is an acute angle.Any triangle with an angle that measures 90 degrees is known as a right triangle.
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
An angle that measures between 0 and 90 degrees is an acute angle.
